一、过去分词作表语
1.过去分词可放在连系动词be,get,feel,remain,seem,look,become等之后作表语,表示主语所处的状态。
常见的这种过去分词有:
be interested be surprised be astonished be amazed
be moved be exhausted be worried be devoted
be pleased be inspired be encouraged be excited
be delighted be satisfied be scared be inspired
be encouraged be excited …
The library is now closed.(状态)
图书馆现在关闭了。
The cup was broken by my little sister yesterday.(动作)
昨天我妹妹把杯子打碎了。
2.过去分词作表语时与被动语态的区别
过去分词作表语时,强调主语所处的状态;而动词的被动语态表示主语是动作的承受者,强调动作。
We were amazed at what he said at the meeting.
我们对他在会上讲的话很是惊讶。
His words were discouraging, which made many people discouraged.
他的话令人泄气,使得很多人灰心丧气。
3.感觉类及物动词的现在分词与过去分词作表语的区别
过去分词作表语多表示人自身的感受或事物自身的状态,常译作“感到……的”;现在分词多表示事物具有的特性,常译作“令人……的”。
I quickly lower myself, ducking my head to avoid looking directly into his eyes so he doesn’t feel ____________(challenge). (2018•全国卷Ⅲ)
答案:challenged
解析:考查词性转换之动词变为形容词。连系动词feel后要接形容词作表语。challenged adj. 受到挑战的;challenging adj. 困难的,富有挑战性的。由语境可知,填challenged。
I’m _________ (interest) in reading novels, __________(write) by Jin Yong.
我对金庸的小说很感兴趣。
答案:interested;written
1.过去分词作时间状语
过去分词作时间状语时,相当于时间状语从句。可在过去分词前加上连词when,while,until等,使其时间意义更明确。
二、过去分词作状语
过去分词表示完成或被动,作状语时,表示动作发生的背景或者情况,在意义上相当于一个状语从句,其省略的主语(逻辑主语)是主句的主语,且与主语之间存在被动关系。过去分词作状语可以表示时间、原因、条件、方式、让步等。
过去分词的否定式是将not放在其前面。
Left (=When it was left) to itself in the room, the baby began to cry.
当被独自留在房间里时,婴儿哭了起来。
2.过去分词作原因状语
过去分词作原因状语时,可转换为由since,because或as引导的原因状语从句,这类状语多放在句子的前半部分。
Choked (=Because he was choked) by the heavy smoke, he could hardly breathe.
他被浓烟呛到了,几乎不能呼吸了。
3.过去分词作条件状语
过去分词作条件状语时,可转换为由if,once或unless等引导的条件状语从句。
Grown (=If they are grown) in rich soil, these seeds can grow fast.
如果被种在肥沃的土壤里,这些种子能长得很快。
4.过去分词作让步状语
